Hot sale Zinc Alloy Die Casting - The Semi-solid Die Casting Process – LongPan

Circuit boards (PC boards): Our aluminum heat sinks can provide a highly effective heat management process for circuit boards by providing a precise combination of vertical and horizontal cooling. Various thicknesses and customized forms are also easily achievable.

High powered lasers: We can produce electronically controlled heat sinks for high-powered laser diodes that offer superior temperature control and high-heat flux-handling capabilities.

Audio equipment: We manufacture heat sinks that are essential equipment for audio amplifiers that can effectively dissipate output transistor heat.

Communication equipment (such as cellular & satellite devices): We’re also leading aluminum heat sink manufacturers for various types of communication equipment that is lightweight and offers excellent resistance against corrosion.

Any application where heat is generated and needs to be removed: Regardless of your application, you can trust LongPan to develop a customized heat sink that can meet your requirements. We’ll work closely with you to design and manufacture the best solution for your needs and budget.

The Benefits of Die Cast Aluminum Heat Sinks

Aluminum die cast heat sinks are electrically conductive, which means they can be electrically grounded – there’s no need to pay additional costs for copper plating, and heat sink parts are used for RF and EMI shielding. Die cast aluminum heat sinks are robust and can be molded with many features included to eliminate secondary operations such as machining and assembly to reduce costs.

Aluminum thermal heat sinks are specially designed to extract heat from components in electronic devices – and they’re designed in a way to need less machining than other processes such as extruded heat sinks or machined heat sinks. The cooling fin, mounting holes and mounting features can be manufactured simultaneously. Die cast heat sinks can be used as raw parts without any finish, or they can be anodized or powder coated for improved surface protection and corrosion resistance.

Besides the common “fin” design of heat sinks die casting can produce “pin fin” designs with greater density in a given area of the product. “Pin fin” features also offer the product designer greater latitude in orientation of the product in the final use – no matter which direction the product is oriented the heat will still flow properly through the “pin fins” thus extracting heat at the best rate possible.
